SPECIFICATION forming part of Letters Patent No. 590,886, dated September 28, 1897. Application tiled February l0, 1897. Serial No. 622,744. (No model.) Y

chines which is simple and Y"durable in'con'` struction and Aarranged to be conveniently folded'while transportingr the machine'from place to place and adapted to be turned in any desired direction when in use to discharg the straw to any desired point.

'Ihe invention consists of certain parts and details and combinations of the same, as willl be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accom panying drawings, forming a part of this specification, in which similar characters of reference indicatecorresponding parts in both views.

Figure l is a side elevation of the improve-A ment as applied, and Fig. 2 is a-plan View of the same with parts broken out. y

On the rear end of the lower sill A of the separator-frame A is secured an auxiliary frame B, carrying a vertically-disposed pivot O, on which is mounted to turn the turn-table D, provided with suitable bearings for a transversely-extending shaft E, connected by well-known suitable means with a part of the threshing-machine, so that the'shaft E is r0- tated when the threshing-machine is set'in motion. On the shaft E is hung the lower section F of the apron-frame F, provided with an upper section F2,'pitotally connected at with the upper end of the lower section F.' The upper section F2 when in use is swung into such a position as to be in alinement with the lower section F', as shown in the drawings, or folded upon the under side there- Y of (see dotted lines, Fig. l) when the device is not in use and the machine is transported from one place to another. Suitable hooks F4 and eyes F5 are then used to hold the sections together.

On the shaft E and within the section F of the apron-frame is secured a pulley Gr, over which passes the apron or slat belt H, also passing over a series of rollers G', journaled inthe sides of the sections F' and F2, to finally passover thepulley G2, held in the outer end of the section F2. The apron or slat belt H is preferably provided on its outer face with transverse slats II/, each containing a row of I outwardly-projecting pins H2 to securely hold the'straw and chaff in place on the belt,while thelatter has a traveling motion and carries the material from the machine to the stack, it beingunderstood that the material is dis- The section F is adapted to be temporarily llocked when in an inclined position to the ative to the section F' I provide the follow- ,ing device: In the outer end of the turn-ta- Ible 'D is j ournaled a transversely-extending drum J, having a suitable handle J', adapted lt'o be taken hold of by the operator for turn- -ring the drum to wind up or unwind thereon, `the Aropes K extending on the sides of the stacker, as indicated in the drawings.

Each of the ropes K extends from the drum or wind- -lass J over pulley L, journaled in the corresponding side of the section F', near the up- `per end thereof. vThe rope thence extends .naled in'the corresponding outer end of a transversely-extending equalization-beam N,

provided at its middle with a ring or staple N2, hung on an arm or equivalent holder O, attached to the upper sill A2 of the separatorframe A, the said support slightly projecting rearwardly beyond the sill, as shown in the drawings. The ropes K afterleaving the pulley N extend outwardly and are rigidly fastened at L2 to the corresponding sides of the section F2, near the outer endthereof and near the bottom of the same, as plainly indicated in Fig. l. A pulley L is arranged near the inner end of the section F to be engaged by the corresponding rope K when the section F2 is to be folded. Now it will be seen that when the several parts are in the position shown in Fig. 1 and the operator turns the .charged upon the stack from the apron or slat vbelt II at the pulley G2.

ICO

drum J so as to wind up the two ropes K simultaneously a pull is exerted in an upward direction on the section F2, so as to swing the same and the section F' upwardly, according to the increase in the height of the stack formed. The material is now discharged at the pulley G2 at a higher elevation.

When it is desired to discharge the material to a lower point, the operator turns the drum J in a reverse direction, so as to unwind the ropes K simultaneously and to permit the sections F' F2 to swing downward by their own weight until the desired point is reached for the material to be discharged at the pulley G2.

Vhen it is desired to fold the section F2 onto the under side of the section F', as previously mentioned, the section F' is brought in such a position that the braces I can be engaged with the staples I. When this has been done, the windlass J is turned to unwind the ropes K to permit the section F2 to swing downward from the hinge F3 on the now iixed outer end of the section F'. During the downward-swinging motion of the section F2 the ropes K engage the pulleys L', previously mentioned. The section F2, when a vertical position is reached, is swung upward and inward by hand against the under side of the section F' and fastened thereto by the hooks and eyes F4 and F5. The braces I are now disconnected from the staples I' and connected with staples I2 and the section F is permit-ted to swing by its own weight downward on a further turning of the windlass to unwind the ropes K. lVhen the stacker-sections F F2 are to be extended, the windlass is turned to wind up the ropes K to swing section F upward to permit of connecting the braces I with the staples I'. The section F2 is now unhooked from section F' and permitted to swing downward into an approximately Vertical position. The operator now actual es the windlass to wind up the ropes K. As the latter pass over the pulleys L an upward pull is exerted on the section F2 to swing the same into alinement with the section F, as shown. The bracesI are then again disconnected to permit of swinging the extended sections up or down, according to the height ot' the stack. By having the transverse beam N hung on the support 0 the said beam is free to swing in any desired direction, so that when the turn-table D is turned on the pivot C thesaid beam N assumes a corresponding position to the stacker-frame F and the section F2 can be swung up or down by winding up or unwinding the ropes K on the drum J, as before explained.

The several pulleys L L L and N N/ are specifically described as pulleys, but, as will be readily understood, they are generically guides, and any equivalent guide may be elnployed in practice.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A stacker, comprising a turn-table, an apron-shaft j ournaled on the said turn-table, an apron-frame hung on the said shaft and made in two sections hinged together, one section being adapted to be held in an inclined fixed position relative to the turn-table, an equalization-beam hung on a support attached to the separator-frame, a windlass journaled on the turn-table, and ropes connected with the said windlass and the outermost section of the apron frame, the said ropes passing over pulleys held on the said sections and on the said equalization-beam, substantially as shown and described.

2. The combination of a turn table, an apron-frame hung on the turn-table so as to swing vertically, the apron-frame comprising inner and outer sections having a hinge connection, ropes at the sides of the apron-frame for raising and lowering the frame-sections, an equaliZing-bar supported above the apronfra-nie, pulleys on the equaliZing-bar, pulleys on t-he inner ysec-tion of the apron-frame, pulleys on the outer section of the apron-frame adjacentto the inner end and means for winding the ropes, said ropes being connected with the said outer section and passing over the pulleys on the equalizing-bar, and overthe pulleys on the said inner frame-section, the pulleys on the said outer section serving to engage and guide the adjacent runs of the ropes when the said outer frame-section is being raised and lowered, substantially as described.

3. In a stacker,1he combination ot' an apronframe, comprising two sections havinghinged connection, the outer section being adapted to be lowered from a position in line with the inner section, ropes connected with the outer section and capable of raisingthc same, overhead guides, above the apron-frame for guiding the ropes, guides located on the inner seetion of the apron-frame and over which the ropes also pass, and additional guides for the ropes, said additional guides being located at the inner e'nd of the outer section and serving to engage the ropes when the outer seetion is being lowered.
